Line a 9-in. pie plate with pastry; trim pastry to 1/2 in. beyond edge of plate and flute edges. Sprinkle macadamia nuts and hazelnuts into the pastry shell. Arrange cashews, pecans and almonds over the chopped nuts.
In a small bowl, beat the eggs, corn syrup, sugars, butter, vanilla and salt until well blended. Pour over nuts.
Bake at 350° for 45-50 minutes or until a knife inserted in the center comes out clean. (Cover edges with foil during the last 10 minutes to prevent overbrowning if necessary.) Cool on a wire rack. Store in the refrigerator.
